IMPROVEMENT IN BIRD-CAGE P-ERCHES.

Specification forming part of Letters Patent No.1 8 1,526, dated August 29, 1.876 application Iiled v July 31, 1876. v l 4 -wi-ll enable others skilled in the art to make and use the same, reference-being had to the accompanying drawings, in which- Figure lis a geometrical elevation of the perch in proper position between the wires of a bird-cage. Fig. 2 is a vertical longitudinal section through the center of the perch. Fig. 3 is a cross-section through the stick or perch. Fig. 4 shows one end of perch with ferrule, and having cap removed.

Similar letters of reference indicate like parts.

The object of my invention is to form a conven'ient retreat, during the day, for insects that iufest birds and fowls during the night, in a place easily accessible, and from which they may be removed and destroyed.

My invention consists of a hollow perch, (represented by Fig. l) into which the insects creep through the lateral apertures aand a', and from which they may be removed by removing the screw-caps b b', or by unserewing the parts c c', Aby means of the screw-joint at or plain, with niche l, better .shown by Fig.

4, clasping the wires of the cage, or otherwise attached to the sides of the cage or apartment where birds or fowls are confined. The perch may be of any desired shape, length, or size, having au internal cavity, e, of any` desired size or-shape, running the entire length of the perch. a a are small lateral openings ot' any desired number from outside into the cavity. B is an adjustable screw-joint lengthening or shortening the perch tol suit a large or small cage or apartment; also, for removing insects. g, in Fig. 4, is an inner i'errule for protection of the end of the perch. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, 'is-v A bird-perch, having the internal longitudinal cavity and the lateral apertures, also hav'- ing the medial screw-joint and terminatingcaps, substantiallyjas described and shown,'

for the purposes above set forth.
